Systems and methods for partitioning a video feed to segment live player activity

ABSTRACT

A process to partition a video feed to segment live player activity includes receiving, on a first recurring basis, a transmission of a central video feed from a first camera. The central video feed is calibrated against a spatial region represented in at least two dimensions that is encompassed by the central video feed. The process includes receiving, on a second recurring basis, a respective time-stamped position information from each tracking device in a plurality of tracking devices. Each tracking device is worn by a corresponding subject on the spatial region and transmits positional information that describes a time-stamped position of the corresponding subject in the spatial region. The process uses the received information and the calibration to define a first sub-view of the central video feed associated with a first subject. The first sub-view comprises a corresponding sub-frame associated with the first subject.

This application claims priority to U.S. Provisional Patent ApplicationNo. 62/795,020, entitled SYSTEMS AND METHODS FOR PARTITIONING A VIDEOFEED TO SEGMENT LIVE PLAYER ACTIVITY filed Jan. 22, 2019, and claimspriority to U.S. Provisional Patent Application No. 62/802,186, entitledSYSTEMS AND METHODS FOR PARTITIONING A VIDEO FEED TO SEGMENT LIVE PLAYERACTIVITY filed Feb. 6, 2019, both of which are incorporated herein byreference for all purposes.

BACKGROUND OF THE INVENTION

Conventional camera tracking systems track an object via an analysis ofthe subject matter that is captured by each respective camera. Forinstance, a series of images is captured by a camera, and these imagesare analyzed to determine optical characteristics of an object that istracked, such as identifying a color associated with the object or asilhouette of the object. These optical characteristics are recognizedin further images, allowing the object to be tracked through theprogression of the series of images. However, these conventional systemsare susceptible to losing track of the object if the object quicklydarts out of a line of sight of the camera or if there are multipleobjects in the line of sight of the camera that are optically similar tothe desired object. Hence, there is a need for improved object trackingand display systems.

BRIEF SUMMARY

Techniques (including a system, a processor, and a computer programproduct) to partition a video feed to segment live player activity aredisclosed. In various embodiments, a process to partition a video feedto segment live player activity includes receiving, on a first recurringbasis, a transmission of a central video feed from a first camera. Thecentral video feed calibrated against a spatial region represented in atleast two dimensions that is encompassed by the central video feed. Theprocess receives, on a second recurring basis, a respective time-stampedposition information from each tracking device in a plurality oftracking devices, wherein each tracking device in the plurality oftracking devices (a) is worn by a corresponding subject in a pluralityof subjects participating in a competition on the spatial region and (b)transmits positional information that describes a time-stamped positionof the corresponding subject in the spatial region. The process uses thereceived time-stamped position information and the calibration of thecentral video feed to define a first sub-view of the central video feed.The first sub-view is associated with a first subject included in theplurality of subjects and the first sub-view comprising for each of aplurality of frames comprising the central video feed a correspondingsub-frame associated with the first subject. The process causes thefirst sub-view to be communicated to a device configured to display thefirst sub-view.

Techniques to partition a video feed to segment live player activity aredisclosed. These techniques enable subject matter of interest to bebetter tracked compared with conventional object tracking methods. Inthis regard, a central video feed can be partitioned into sub-views of asubject of interest. For example, a video feed of a view of a footballgame on a playing field is partitioned into isolation shots of aspecific player or group of players allowing a spectator (e.g., a fan,coach, etc.) to track the specific player or group of players throughoutthe game. Conventionally, when a camera pans away from a specificplayer, a spectator can no longer keep track of that specific player. Byusing the techniques for partitioning a video feed disclosed herein, aspectator can visually track a specific player throughout the gamewithout interruption.

In various embodiments, processor 100 includes a machine learning engine210 (not shown in FIG. 1) that facilitates the prediction of the outcomeof a competitions. The next figure describes an example of processor 100that includes a machine learning engine in greater detail.

FIGS. 2A and 2B show a block diagram illustrating an embodiment of asystem for partitioning a video feed to segment live player activity. Asdepicted in FIG. 2A, an array of anchor devices 120 receives telemetrydata 230 from one or more tracking devices 300. In order to minimizeerror in receiving the telemetry from the one or more tracking devices300, the array of anchor devices 120 preferably includes at least threeanchor devices. Inclusion of at least three anchor devices 120 withinthe array of anchor devices allow for each ping (e.g., telemetry data230) received from a respective tracking device 300 to be triangulatedusing the combined data from the at least three anchor that receive therespective ping. Additional details and information regarding systemsand methods for receiving pings from tracking devices and theoptimization thereof will be described in more detail infra, withparticular reference to at least FIGS. 3 and 4.

In the example shown, the telemetry data 230 that is received by thearray of anchors 120 from the one or more tracking devices 300 includespositional telemetry data 232. The positional telemetry data 232provides location data for a respective tracking device 300, whichdescribes a location of the tracking device within a spatial region. Insome embodiments, this positional telemetry data 232 is provided as oneor more Cartesian coordinates (e.g., an X coordinate, a Y coordinate,and/or Z a coordinate) that describe the position of each respectivetracking device 300, although any coordinate system (e.g., polarcoordinates, etc.) that describes the position of each respectivetracking device 300 is used in alternative embodiments.

The telemetry data 230 that is received by the array of anchors 120 fromthe one or more tracking devices 300 includes kinetic telemetry data234. The kinetic telemetry data 234 provides data related to variouskinematics of the respective tracking device. In some embodiments, thiskinetic telemetry data 234 is provided as a velocity of the respectivetracking device 300, an acceleration of the respective tracking device,and/or a jerk of the respective tracking device. Further, in someembodiments one or more of the above values is determined from anaccelerometer (e.g., accelerometer 317 of FIG. 3) of the respectivetracking device 300 and/or derived from the positional telemetry data232 of the respective tracking device. Further, in some embodiments thetelemetry data 230 that is received by the array of anchors 120 from theone or more tracking devices 300 includes biometric telemetry data 236.The biometric telemetry data 236 provides biometric information relatedto each subject associated with the respective tracking device 300. Insome embodiments, this biometric information includes a heart rate ofthe subject, temperature (e.g., a skin temperature, a temporaltemperature, etc.), and the like.

In some embodiments, the array of anchors 120 communicates the abovedescribed telemetry data (e.g., positional telemetry 232, kinetictelemetry 234, biometric telemetry 236) to a telemetry parsing system240. Accordingly, in some embodiments the telemetry parsing system 240communicates the telemetry data (e.g., stream of data 244) to a machinelearning engine 210 and/or a real time data packager 246 for furtherprocessing and analysis.

In some embodiments, the real time data packager 246 synchronizes one ormore data sources (e.g., streaming data 244 from telemetry parsingsystem 240, game statistics input system 250, machine learning engine210, etc.) by using one or more timestamps associated with therespective data. For instance, in some embodiments the data sourcesprovide data that is associated with a real world clock timestamp (e.g.,an event occurred at and is associated with a real world time of 1:17P.M.). In some embodiments, the data sources provide data that isassociated with a game clock timestamp related to a live sports event(e.g., an event occurred with 2 minutes and 15 seconds remaining in thesecond quarter). Moreover, in some embodiments the data sources providedata that is associated with both the real world clock timestamp and thegame clock timestamp. Synchronization of the data sources via timestampsallows for a designer of the present disclosure to provide services withan additional layer of accuracy, particularly with betting and wageringon outcomes at a live event. For instance, in some embodiments dataprovided to a user device 700 (e.g., streaming data 280 and/or directdata 282 of FIG. 2B) describes the wagering (e.g., odds) on a next playin a football game. In order to determine if an end user of the userdevice 700 places a wager within a predetermined window of time (e.g.,before the snap of the ball of the next play), the game clock and realworld time data received from the user device and/or communicated to theuser device are analyzed and the wager is either validated, rejected, orheld for further consideration.

In some embodiments, machine learning engine 210 receives data fromvarious sources of the present disclosure in order to predict a futureoutcome at a live sporting event and generate statistics for analysisand use. For instance, in some embodiments the data sources of themachine learning engine 210 includes a positional data formationclassifier 212, hereinafter “neural net,” that provides informationrelated to various configurations and formations of players at any givenpoint of time in game. For instance, in some embodiments the formationclassifier 212 parses the telemetry data 230 to analyze pre-snapformations of players. The analyses of the pre-snap telemetry data 230allows for the formation classifier 212 to determine various states andconditions of the game, such as a down of a game, a positional ruleviolation within a game (e.g., off-sides, illegal motion, etc.), and thelike. Moreover, in some embodiments the formation classifier 212analyzes telemetry data 230 that is received subsequent the start of theplay in order to further generate data and information related to howeach formation evolves (e.g., an expected running route versus an actualrunning route, an expected blocking assignment versus an action blockingassignment, a speed of a player throughout a play, a distance betweentwo players throughout a play, etc.).

In some embodiments, machine learning engine 210 includes a historicaltraining data store 214. Historical data store 214 provides historicaldata and information related to each particular sport (e.g., sportshistorical data 508 of FIG. 5), each particular team associated with theparticular sport (e.g., team historical data 510 of FIG. 5), and/or eachparticular player associated with the particular sport and/or team(e.g., player historical data 514 of FIG. 5). In some embodiments, thisdata is initially used as a training data set for the machine learningengine 210. However, the present disclosure is not limited thereto asthis data may also be used to further augment the features and servicesprovided by the machine learning engine 210 and other systems of thepresent disclosure.

Further, in some embodiments the machine learning engine 210 includes avariety of models 220 that are utilized to predict a future outcome of asporting event and provide analysis of the sporting event. In someembodiments, the models 220 of the machine learning engine 210 includean expected points model 222. The expected points model 222 provides alikelihood of receiving points for a particular play at the event via anumerical value. In some embodiments, the models 220 of the machinelearning engine 210 include a win probability model 224 that provideseither a likelihood of each participating team of the event to win or alikelihood of any given point spread between the winning and losingteams at the event. Furthermore, in some embodiments the models 220 ofthe machine learning engine 210 include a player based wins abovereplacement (WAR) model 226. The WAR model 226 provides a contributionvalue a respective player adds to their corresponding team (e.g., player1 provides a value of 1 to a respective team and player two provides avalue of 2 to the respective team, therefore player two is worth more tothe respective team).

In some embodiments, machine learning engine 210 include a situationstore 228. The situation store 228 is a cache of various situationaldetails and/or statistics that is accessed rapidly during a real gamescenario. Rapid access to the situation store 228 prevents lag thatwould otherwise be induced from querying different databases and systems(e.g., positional data formation classifier 212, historical trainingdata 214, etc.) in order to obtain the same information. Additionaldetails and information regarding the machine learning engine and thecomponents therein, including the various above described data storesand models, will be described in more detail infra, with particularreference to at least FIGS. 5 and 6.

Machine learning engine 210 communicates various odds and outputs of thevarious databases and models therein to an odds management system 600.In communicating with the machine learning engine 210, the oddsmanagement system 600 provides various wagers and predictive odds forfuture events at a sporting event to the user devices 700, while alsoupdating these odds in real time to reflect current situations andstatistics of a game.

As depicted in FIG. 2B, in some embodiments system 48 includes a gamestatistics input system 250. The game statistics input system 250 isconfigured for providing at least in play data 254, which, in examplecase of football, describes a state of the game during a given play(e.g., a weak side receiver ran a post route), as well as end of playdata 256, which describes a state of the game after a given play (e.g.,a play resulted in a first down at the opponents 42-yard line). In someembodiments, the data of the statistics input system 250 is associatedwith the world and game clock 242, and accordingly is communicated tothe telemetry parsing system 240 and/or the machine learning engine 210.In some embodiments the game statistics input system 250 is subsumed bythe formation classifier 212.

In some embodiments, various data is communicated to an applicationprogramming interface (API) server 260. This data may include streamingdata 244, end of play data 256, data from the odds management system600, or a combination thereof. Accordingly, the API server 260facilitates communication between various components of the system 48,one or more user devices 700, and a master statistics database 270 inorder to provide various features and services of the present disclosure(e.g., a stream of the game, a request for statistics, placing a wageron a play, etc.). Communication between the API server 260 and the oneor more user devices 700 includes providing streaming data 280 and/ordirect data 282 to each respective user device 700 through thecommunications network 106, as well as receiving various requests 284from each respective user device. By way of non-limiting example,streaming data 280 includes tracking “telemetry” data including xyzcoordinates of players or accelerometer data of players, direct data 282includes clock, score, or remaining timeouts.

In some embodiments, the master statistics database 270 includes some orall of the statistics known to the machine learning engine 210 that areobtainable to a user. The master statistics database is updatedregularly such as at the end of every play or every few plays. Forinstance, in some embodiments only a portion of the statistics known tothe machine learning engine 210 is desired to be obtainable by a user,and thus is stored in the master statistics database 270. However, thepresent disclosure is not limited thereto. For instance, in someembodiments the master statistics database 270 is subsumed by themachine learning engine 270. Elements in dashed boxes are optionalcombined as a single system or device.

Now that an infrastructure of the system 48 has been generallydescribed, an exemplary tracking device 300 will be described withreference to FIG. 3.

In some embodiments,the information stored by the tracking device identifier module 305includes a tracking device identifier (ID) 306 that includes a unique ID(e.g., a serial number or a code) representing the respective trackingdevice 300. In some embodiments, the tracking device ID module 305includes a tracking device group ID 307 that designates the respectivetracking device 300 to one or more groups of tracking devices (e.g.,tracking device group 418-2 of FIG. 4). Further, in some embodimentspings communicated by the respective tracking device 300 includes dataof the tracking device ID module 305, allowing for an array of anchordevices 120 to identify pings received from more than one trackingdevice. Additional details and information regarding the grouping of atracking device 300 will be describe in more detail infra, withparticular reference to at least FIG. 4.

The tracking device ping module 308 stores data and information relatedto various ping parameters and conditions of respective tracking device300, as well as facilitating management of the ping. For instance, insome embodiments the tracking device ping module 308 manages aninstantaneous ping rate 310 of the respective tracking device 300 (e.g.,managing an instantaneous ping rate 310 to be 10 Hertz (HZ)). In someembodiments, the tracking device 300 is configured with one or more pingrate limits, including one or more both of a minimum ping rate 312 and amaximum ping rate 314, that define a maximum and a minimum ping ratethat the tracking device 300 may transmit pings. For instance, in someembodiments the minimum ping rate 312 and/or the maximum ping rate 314may be set by the tracking device management system 400 based upon oneor more of bandwidth limitations, a number of active tracking devices300, and a type of expected activity (e.g., a sport and/or event types,an expected subject activity, etc.). When configured with one or bothping rate limits, the tracking device ping module 308 operates to adjustthe instantaneous ping rate 310 between the minimum ping rate 312 andthe maximum ping rate 314. Thus, automatic optimization of trackingmanagement system 400 may be used in combination with automatic pingrate adjustment of tracking device 300. In some embodiments, trackingdevice ping module 308 is configured to compare detected motion fromaccelerometer 317 to a predefined threshold 316. Accordingly, the pingmodule 308 increases the instantaneous ping rate 310 in accordance witha determination that the detected motion is greater than predefinedthreshold 316 (e.g., until the instantaneous ping rate 310 reaches themaximum ping rate 314). Likewise, the ping module 308 decreases theinstantaneous ping rate 310 (e.g., until the instantaneous ping rate 310reaches the minimum ping rate 312) in accordance with a determinationthat the detected motion is less than the threshold ping rate 316.

In some embodiments, the ping module 310 includes a variable ping rateflag 318, which is configured (e.g., set wirelessly) by the trackingdevice management system 400, that determines whether ping module 308automatically, or not, changes the instantons ping rate 310 based upondetermined activity. For example, the tracking device management system400 may set variable ping rate flag 318 to “false” for one or moretracking devices 300 that is associated with a player not currentlyparticipating on the field of play, wherein instantaneous ping rate 310remains at a low rate even if the player is actively warming up forexample. Tracking device management system 400 sets variable ping rateflag 318 to “true” for one or more players that is activelyparticipating on the field of play. Furthermore, in some embodimentseach tracking device 300 is dynamically configured based upon a locationof the respective tracking device. For instance, in accordance with adetermination that a tracking device 300 is within a field of play(e.g., if a player is actively participating in a game) as opposed to adetermination that the tracking device is off the field of play (e.g.,if a player is not actively participating in a game).

Utilizing the tracking device ping model 308 and/or the sensor (e.g.,accelerometer 317 and/or optional sensors 364) within tracking device300 increases reliability of the system 48 (e.g., the array of anchors120, the telemetry parsing system 240, the tracking device managementsystem 400, etc.) to track subjects disposed with the tracking device.

As previously described, in some embodiments each tracking device 300provides telemetry data 230 that is received and communicated by variousanchors 120 that are proximate to the respective tracking device 300.This telemetry data includes positional telemetry data 232 (e.g., X, Y,and/or Z coordinates), kinetic telemetry data 234 (e.g., velocity,acceleration, and/or jerk), and/or biometric telemetry data 236 (e.g.,heart rate, physical attributes of a player such as shoulder width,etc.).

In some embodiments, each subject in the game is equipped with more thanone tracking device 300 in order to increase the accuracy of the datareceived from the tracking devices about the subject. For instance, insome embodiments the left shoulder and the right shoulder of arespective subject are both equipped with a tracking device 300, eachsuch tracking device functioning normally and having line of site to atleast a subset of the anchors 120. Accordingly, in some embodiments thedata from the left and right tracking devices 300 have their telemetrydata 230 combined to form a single time-stamped object. This singleobject combines positional data from both tracking devices 300 to createa center line representation of a position of the respective player.Moreover, this center line calculated position provides a more accuraterepresentation of the center of a player's position on the playingfield. Further, using the relative positional data from two trackingdevices 300 positioned on the left and right shoulders of a player,prior to creating the single player object as described above, allowsthe system 48 to determine a direction (e.g., a rotation) that theplayer is facing. In various embodiments, including rotational datagreatly eases the task of creating avatars from data created byrecording telemetry data 230 during a game and/or establishingsophisticated covariates that can be used to better predict futureevents in the game or the final outcome of the game itself.

In some embodiments, the tracking device 300 has any or all of thecircuitry, hardware components, and software components found in thedevice depicted in FIG. 3. In the interest of brevity and clarity, onlya few of the possible components of the tracking device 300 are shown tobetter emphasize the additional software modules that are installed onthe tracking device 300.

Peripherals interface 570 can be used to couple input and outputperipherals of the management system to CPU(s) 574 and memory 502. Theone or more processors 574 run or execute various software programsand/or sets of instructions stored in memory 502 to perform variousfunctions for the statistics system 500 and to process data.

In some embodiments, peripherals interface 570, CPU(s) 574, and memorycontroller 588 are, optionally, implemented on a single chip. In someother embodiments, they are, optionally, implemented on separate chips.

In some embodiments, power system 576 optionally includes a powermanagement system, one or more power sources (e.g., battery, alternatingcurrent (AC)), a recharging system, a power failure detection circuit, apower converter or inverter, a power status indicator (e.g., alight-emitting diode (LED), etc.) and any other components associatedwith the generation, management and distribution of power in portabledevices.

As illustrated in FIG. 5, memory 502 of the remote user devicepreferably stores:

-   -   an operating system 504 (e.g., ANDROID, iOS, DARWIN, RTXC,        LINUX, UNIX, OS X, WINDOWS, or an embedded operating system such        as VxWorks) includes various software components and or drivers        for controlling and managing general system tasks (e.g., memory        management, storage device control, power management, etc.) and        facilitates communication between various hardware and software        components;    -   a positional formation classifier 212 for determining and        analyzing formations of players;    -   a historical training data store 214 for storing various        statistics related to each sport 508, wherein each sport 508        including various team historical data 510 for one or more teams        512, as well as various player statistics 514 for one or more        players 516; and    -   a situational store 228 for storing data related to formations        of players and game situations.

The positional formation classifier 212 (sometimes simply called aformation classifier) provides information related to various states andformations of players at any given point of time in game. For instance,in some embodiments the formation classifier 212 parses telemetry data230 in order to determine pre-snap formations. Accordingly, once aformation is determined and telemetry data 230 is parsed, sub-categoriesof the formation may be determined (e.g., an I-formation with differentsub-categories defining different running backs). Moreover, in someembodiments the formation classifier 212 acts as a virtual referee anddetermines if infractions have occurred within a game or play, such as aplayer being off-sides, a neutral zone infraction, an illegal motion, anillegal formation, and the like. In some embodiments, the formationclassifier 212 includes one or more tables of various formations in afootball game, such as a first table of offensive formations, a secondtable of defensive formations, and a third table of special teamsformations. In some embodiments, the above table of formations providessome or all of the formations described by Table 1, Table 2, and Table3.

TABLE 3 Exemplary Special Teams Football Formations Exemplary FormationField goal formation Kick return formation Kickoff formation Puntformation

Additionally, in some embodiments the formation classifier 212determines a ball carrier by comparing telemetry data 230 provided bythe ball and telemetry data of a player that is closest to the ball.Likewise, in some embodiments determining which team has possession ofthe ball is conducted in a similar manner. Furthermore, in someembodiments the formation classifier 212 determines if a player iswithin a boundary of a game by analyses the telemetry data 230 extractedfrom the player and comparing this with the known boundaries of thefield of play. In this way, the formation classifier 212 parsestelemetry data 230 to provide a box score and/or automatic colorcommentary of a game.

While the formation classifier 212 is labeled a “neural net” it will beappreciated that the formation classifier 212 module does not have toperform classification of team formation using a neural networkclassifier. In some embodiments the formation classifier 212 module doesin fact make use of any classification scheme that can discern a teamformation from telemetry data. For instance, in some embodimentsformation classifier 212 makes use of a nearest neighbor algorithm toperform the classification of team formation. In other embodimentsformation classifier 212 makes use of clustering to perform theclassification of team formation. In some embodiments the elucidation ofthe formation class by formation classifier 212 is used as a covariatein statistical models that predict the outcome of a current live game(e.g., win/loss, point spread, etc.) as disclosed with respect tomethods and features described with respect to FIG. 8.

In more detail, in some embodiments, the formation classifier 212 isbased on a logistic regression algorithm, a neural network algorithm, asupport vector machine (SVM) algorithm, a Naive Bayes algorithm, anearest-neighbor algorithm, a boosted trees algorithm, a random forestalgorithm, or a decision tree algorithm.

By way of non-limiting example the formation classifier 212 is based ona logistic regression algorithm, a neural network algorithm, a supportvector machine (SVM) algorithm, a Naive Bayes algorithm, anearest-neighbor algorithm, a boosted trees algorithm, a random forestalgorithm, or a decision tree algorithm. When used for classification,SVMs separate a given set of binary labeled data training set with ahyper-plane that is maximally distant from the labeled data. For casesin which no linear separation is possible, SVMs can work in combinationwith the technique of ‘kernels’, which automatically realizes anon-linear mapping to a feature space. The hyper-plane found by the SVMin feature space corresponds to a non-linear decision boundary in theinput space. Tree-based methods partition the feature space into a setof rectangles, and then fit a model (like a constant) in each one. Insome embodiments, the decision tree is random forest regression. Onespecific algorithm that can serve as the formation classifier 212 forthe instant methods is a classification and regression tree (CART).Other specific decision tree algorithms that can serve as the formationclassifier 212 for the instant methods include, but are not limited to,ID3, C4.5, MART, and Random Forests.

In some embodiments, the historical data store 214 stores statisticsrelated to each sport 508, each team 510 within the sport league, aswell as the respective players 512. As previously described, in someembodiments the data stored in the historical data store 214 is utilizedas a training set of data for machine learning engine 210 and/orformation classifier 212. For instance, in some embodiments the datastored in the historical data store 214 is utilized as an initial dataset at a start of a league, as in inferred from other data sets ofsimilar league (e.g., using college football stats if a player is aprofessional rookie), or utilized to create data points if a newstatistic is being generated (e.g., a previously unknown statisticbecomes relevant). Furthermore, in some embodiments data from apreviously played game is stored within the historical data store 214.

In some embodiments, the situation store 228 includes data stored in oneor more databases of the machine learning engine 210 as a cache ofinformation. This cache of the situation store 228 allows for data to bequeried for and utilized rapidly, rather than having to query eachrespective database. In some embodiments, the situation store 288creates a new cache of data for each respective game. However, thepresent disclosure is not limited thereto.

As previously described, the modelling engine 200 includes variousalgorithms and models utilized for generating statistics and predictingoutcomes at a sports event. In some embodiments, these models includethe expected points model 222 that provides a numerical value for eachplay of a game. For instance, if a drive in a game that results in atouchdown has plays that include a 5-yard rush, a 94-yard pass, and a1-yard rush, even though the 1-yard rush resulted in the touchdown the94-yard pass has a much more significant role in the drive. Thus, insome embodiments the 5-yard rush is allocated an expected points valueof 0.5, the 94-yard pass is allocated an expected points value of 5.5,and the 1-yard rush is allocated an expected points value of 1, withhigh values indicating more important or game defining plays. In someembodiments modelling engine 200 uses the telemetry data collected inaccordance with the present disclosure to predict the outcome of a game(e.g., win/loss, point spread, etc.) as disclosed with respect tomethods and features described with respect to FIG. 8.

In some embodiments, the real time game situation module 614 receivesinformation related to situations occurring in a game. This informationis then utilized in adjusting various weights and values in the abovedescribed models.

Now that a general topology of the system 48 has been described, methodsfor partitioning a video feed to segment live player activity will bedescribed with reference to, at least, FIGS. 1 through 7.

FIG. 8 is a flow chart illustrating an embodiment of a process partitiona video feed to segment live player activity. This process may beimplemented by processor 100 in cooperation with user device 700 and theother devices of system 48 described above.

At 802, process 800 receives, on a first recurring basis, a transmissionof a central video feed from a first camera. Referring to FIG. 10A, acentral video feed 1000-A is received from a first camera 140, forexample. In some embodiments, the camera 140 is a fixed camera (e.g.,the camera is limited in movement in at least one axis). For instance,in some embodiments the camera 140 is fixed such that the camera iscapable of having a variable tilt, pan, and/or zoom, but is not able tobe physically moved to another location. The camera can be disposed in avariety of locations and orientations such as at a first end portion(e.g., a half court line, a 50-yard line) of a field of play in alandscape orientation or at a second end portion (e.g., an end zone, agoal) of a field of in a portrait orientation, among others. The camera140 is in communication with a network (e.g., communications network106) in order to communicate with one or more devices and systems of thepresent disclosure.

In some embodiments, the central video feed comprises and/or is includedin a plurality of central or other video fees, each generated by one ormore cameras located and oriented to generate video of at least aportion of the field of play. In some embodiments, the central videofeed and/or another video feed may be generated at least in part bycombining video data generated by a plurality of cameras, such as acomposite or otherwise merged or combined video.

The central video feed is calibrated against a spatial regionrepresented in at least two dimensions that is encompassed by thecentral video feed. In some embodiments, the spatial region is a regionthat is captured by an array of anchor devices 120. The spatial regioncan be a field of play of a live sports event (e.g., field of play 902of FIG. 9).

In some embodiments, the calibration of the central video feed includesdetermining an equivalent portion of the central video feed for thecoordinate system used by the positional information (e.g., telemetrydata 230). Since standard fields of play of competitive sports includeboundary lines of regulation, uniform length and thickness/widths (e.g.,an out of bounds line, a half court line, a yard line, etc.), theselengths and thicknesses can be used to determine coordinate positions inthe video feed. For instance, if a line on a field of play is known tohave a uniform thickness (e.g., 6 centimeters thickness) and thethickness of the line in the central video seen is determined to reducelinearly from a first thickness to a second thickness, then an exactlocation of a subject with respect to the line can be determined in thecentral video feed.

At 804, the process receives, on a second recurring basis, a respectivetime-stamped position information from each tracking device in aplurality of tracking devices, where each tracking device in theplurality of tracking devices (a) is worn by a corresponding subject ina plurality of subjects participating in a competition on the spatialregion and (b) transmits positional information that describes atime-stamped position of the corresponding subject in the spatialregion.

A respective transmission of time-stamped positional information (e.g.,telemetry data 230) is received from each tracking device 300 in aplurality of tracking devices. The recurring basis of receiving thetransmission of time-stamped positional information can be a ping rate(e.g., instantaneous ping rate 310 of FIG. 3) of a respective trackingdevice 300. In some embodiments, transmission of time-stamped positionalinformation from each tracking device in a plurality of tracking devicesoccurs at a bandwidth of greater than 500 MHz or a fractional bandwidthequal to or greater than 0.20. By way of non-limiting example, thetransmission of time-stamped positional information from each trackingdevice in a plurality of tracking devices is within 3.4 GHz to 10.6 GHz,each tracking device 300 in the plurality of tracking devices has asignal refresh rate of between 1 Hz and 60 Hz, and/or the recurringbasis is between 1 Hz and 60 Hz. Each tracking device 300 of theplurality of tracking devices sends a unique signal that is received bythe receiving, identifying a respective tracking device. Each trackingdevice can transmit biometric data (e.g., biometric telemetry 236)specific to a respective subject associated with the respective trackingdevice if biometric data is collected.

Each tracking device 300 is worn by a corresponding subject in aplurality of subjects that is participating in a competition on thespatial region. Further, each tracking device 300 transmits positionalinformation (e.g., telemetry data 230) that describes a time-stampedposition of the corresponding subject in the spatial region. In someembodiments, there are at least two tracking devices 300 worn by eachsubject in the plurality of subjects. Each additional tracking device300 associated with a corresponding subject reduces an amount of errorin predicting an actual location of the subject.

In some embodiments, the plurality of subjects includes a first team(e.g., a home team) and a second team (e.g., an away team). In someembodiments, the first team and/or the second are included in a leagueof teams (e.g., a football league, a basketball association, etc.). Thefirst team includes a first plurality of players (e.g. a first roster ofplayers) and the second team includes a second plurality of players(e.g., a second roster of players). Throughout various embodiments ofthe present disclosure, the first team and the second team are engagedin a competitive game (e.g., a live sport event), such as a footballgame or a basketball game. Accordingly, the spatial region is a field ofplay of the competitive game, such as a football field or a basketballcourt. In some embodiments, the subjects of the present disclosure areplayers, coaches, referees, or a combination thereof that are associatedwith a present game.

In some embodiments, each time-stamped position in an independentplurality of time-stamped positions for a respective player of the firstor second plurality of players includes an xyz-coordinate of therespective player with respect to the spatial region. For instance, insome embodiments the spatial region is mapped such that a center portionof the spatial region (e.g., half court, 50-yard line, etc.) is anorigin of an axis and a boundary region of the spatial region (e.g., anout of bounds line) is a maximum or minimum coordinate of an axis. Insome embodiments, the xyz-coordinate has an accuracy of ±5 centimeters,±7.5 centimeters, ±10 centimeters, ±12.5 centimeters, ±15 centimeters,or ±17.5 centimeters.

At 806, the process uses the received time-stamped position informationand the calibration of the central video feed to define a first sub-viewof the central video feed. The first sub-view is associated with a firstsubject included in the plurality of subjects and the first sub-viewcomprising for each of a plurality of frames comprising the centralvideo feed a corresponding sub-frame associated with the first subject.

For example, in some embodiments, at 806 the process applies to each ofa plurality of sequential frames of video data a mathematicaltransformation that is based at least in part on correspondingcamera/video calibration data to determine, based on timestamp datacomprising the received positional information and the positionalinformation associated with each timestamp (e.g., XYZ coordinates of asubject A), a subset or portion of each sequential frame that isassociated with the corresponding positional information of the subjectA. The determined subsets/portions of the sequential frames are used toprovide a sub-view of the central video feed associated with the subjectA.

The sub-view is a different resolution from the central video feed invarious embodiments. Despite being a different resolution, the qualitydifference is not necessarily noticeable to the average spectator sothat the viewing experience remains enjoyable. For example, the centralvideo feed is provided at a first resolution (e.g., a native resolutionof the camera 140) such as between 2K and 8K. To this point, in someembodiments the central video feed includes a plurality of fulltwo-dimensional frames (e.g., a first frame associated with a first timepoint, a second frame associated with a second time point, . . . , a nthframe associated with an nth time point). Each respective fulltwo-dimensional frame in the plurality of full two-dimensional frameshas a first dimension size and a second dimension size (e.g., ahorizontal size and a vertical size such as a number of horizontalpixels and a number of vertical pixels). The first sub-view includes acorresponding sub-frame, for each respective full two-dimensional framein the plurality of full two-dimensional frames. Each correspondingsub-frame is a portion of a corresponding full frame (e.g., sub-view1000-B and sub-view 1000-C of FIGS. 10B and 10C, respectively,illustrate instantaneous sub-frames of the central video feed full frame1000-A of FIG. 10A).

In some embodiments, each sub-frame has a third dimension size and afourth dimension size. Moreover, the third dimension size can be a fixedfraction of the first dimension size and the fourth dimension size is afixed fraction of the second dimension size. For instance, the fixedfraction of the first dimension size and the fixed fraction of thesecond dimension size of a same fraction (e.g., 10%, 20%, 30%, . . . ,90%). Similarly, the fixed fraction of the first dimension size can be afirst fraction and the fixed fraction of the second dimension size canbe a second fraction different than the first fraction (e.g., thecentral video feed is captured in a landscape orientation and eachsub-view is partitioned in a portrait orientation). By way ofnon-limiting example, (i) the first dimension size is 7680 pixels andthe third dimension size is 3840 pixels, and the second dimension sizeis 4320 pixels and the fourth dimension size is 2160 pixels; or (ii) thefirst dimension size is 8192 pixels and the third dimension size is 3840pixels, and the second dimension size is 4320 pixels and the fourthdimension size is 2160 pixels. In some embodiments each respective fulltwo-dimensional frame in the plurality of full two-dimensional framesincludes at least 10 megapixels to 40 megapixels (e.g., 10 megapixels,15 megapixels, 20 megapixels, . . . , 40 megapixels).

In some embodiments a sub-view (e.g., the first sub-view) includes acorresponding sub-frame, for each respective full two-dimensional framein the plurality of full two-dimensional frames, that includes less than5 megapixels to 15 megapixels (e.g., 5 megapixels, 7.5 megapixels, 10megapixels, . . . , 15 megapixels).

The time-stamped positional information of the receiving is overlaidonto the central video feed. This overlaying is conducted using thecalibration of the central video feed against the spatial region. Forinstance, if the central video feed is calibrated against the spatialregion using the same coordinate system as the positional information,then the received positional information can be mapped onto the centralvideo feed using the same coordinate system. This overlaying determinesa location of each subject in at least a subset of the plurality ofsubjects in the central video feed. For instance, in some embodimentsthe positional information 230 provides at least an X and Y coordinateof a subject on the spatial region (e.g., field of play 902 of FIG. 9)at a respective time stamp. Since the central video feed has beencalibrated using the same coordinate system as the positionalinformation, the X and Y coordinate of the subject can be equated to alocation in the video feed. This allows for the subject to be tracked inthe central video feed using positional information, instead of trackingthe subject using optical characteristics of the subject (e.g., a colorof the subject, a silhouette of the subject, etc.).

In some embodiments, the time-stamped positional information includes aworld clock time-stamp, a game clock time-stamp, or a combinationthereof (e.g., world and game clocks 242 of FIG. 2). The one or moretime stamps is used by the overlapping to overlap the time-stampedpositional information of the receiving of positional information ontothe central video feed. For instance, if the time stamped positionalinformation consumes a first period of time until received by the system48 and the central video feed consumes a second period of time untilreceived by the system, the time stamps associated with the centralvideo feed and the positional information are compared in order toensure that the overlaying is accurate and precise.

At 808, the process causes the first sub-view to be communicated to adevice configured to display the first sub-view. As described above, afirst sub-view (e.g., sub-view 1000-B of FIG. 10B) of the central videofeed can be defined at a second resolution, that is less than the firstresolution. For instance, the first resolution is at least four times,six times, or eight times the pixel resolution of a second resolution ofa video that is partitioned from the central video feed.

The coordinates of a center of the first sub-view within the centralvideo feed changes over time, without human intervention, in accordancewith a change over time in the position of the first subject asdetermined from recurring instances of the receiving that occur on thesecond recurring basis by the overlapping. In some embodiments, thecenter of the first sub-view is associated with position coordinates(e.g., XYZ) generated by a tracking device worn or otherwise associatedwith the subject. In some embodiments, a subject may wear multipletracking devices and the first sub-view is centered based on a set ofcoordinates generated based on tracking data from the plurality ofdevices. For example, device data from multiple tracking devices worn bya subject may be correlated, e.g., based on timestamp data, and ageometric or other center set of coordinates may be computed based onthe coordinates generated by the respective tracking devices.

In some embodiments, the first sub-view of the central video feed iscommunicated to a remote device (e.g., user device 700 of FIG. 7)independent of the central video feed. Accordingly, the communicatingcauses the remote device to display the first sub-view of the centralvideo feed. By way of non-limiting example, the remote device is ahandheld device such as a smart phone, a tablet, a gaming console, afixed computer system such as a personal home computer, or the like.Moreover, the communicating can occur wirelessly (e.g., wirelessly overnetwork 106).

In various embodiments, at least a first subject in the subset ofsubjects is selected (e.g., selecting sub-view 1000-C of FIG. 10C). Theselection of the at least first subject can be conducted via thecomputer system 48 for example by an operator of the computer system 48(e.g., a video production specialist, a producer, a director, etc.), anend user of each respective remote device (e.g., via a respective userdevice 700), or automatically. For example, a first subject is selectedautomatically based at least in part on proximity (being within athreshold distance) to a ball or other subject (for example, apreviously selected subject with which the subject is associated, suchas in a one-on-one match or by being associated with complementarypositions, such as opposing offensive and defensive linemen). Moreover,a sub-view may be selected from a wider collection of sub-views (e.g., alist of available sub-views, a preview of available sub-view, etc.). Thewider collection of sub-views includes a sub-view for each player activein a competitive game (e.g., twenty-two sub-views for an Americanfootball game). This end-user selection allows for each user to selectone or more subjects according to their desire. For instance, if theend-user has a list of favorite subjects spread across multiple teams,the end-user may view sub-views of each of these favorite subjects on asingle remote device and/or display.

In some embodiments, an identity of the first subject is received at theremote device. For instance, the first sub view includes informationrelated to the identity of the first subject (e.g., a name of the firstsubject). This identity of the respective subject allows for an end-userto quickly identify different sub views when viewing more than one subview. In some embodiments, a tracking device 300 is attached to (e.g.,embedded within) a ball that is being used in the competitive sport onthe spatial region. Accordingly, the identity of the first subject isdetermined, without human intervention, based on a determination ofwhich subject in the plurality of subjects is currently closet to theball using the respective transmission of time-stamped positionalinformation from each tracking device 300.

In various embodiments, one or more steps of process 800 occurs during alive game in which the plurality of subjects is participating. However,the present disclosure is not limited thereto. For instance, thecommunicating can occur after a live game (e.g., such as viewinghighlights of the live game or a replay of the live game).

FIG. 9 shows an example environment including a field of play thatincludes components of a tracking according to an embodiment of thepresent disclosure. An exemplary environment (e.g., stadium 906) 900.The environment 900 includes a field of play 902 in which a game isplayed (e.g., a football game). The environment 900 includes a region904 that includes the field of play 902 and an area immediatelysurrounding the field of play (e.g., an area that includes subjects notparticipating in the game such as subject 930-1 and subject 940-1). Theenvironment 900 includes an array of anchor devices 120 (e.g., anchordevice 1201-1, anchor device 120-2, . . . , anchor device 120-Q) thatreceive telemetry data from one or more tracking devices 300 associatedwith a respective subject of the game. As illustrated in FIG. 9, in someembodiments the array of anchor devices is in communication (e.g., viacommunication network 106) with a telemetry parsing system 240 (e.g.,tracker management system 400 of FIG. 4). Moreover, in some embodimentsone or more cameras 140 (e.g., camera 140-1) capture images and/or videoof the sports event, which is used in forming the virtual reproduction.In FIG. 9, markers 930 represent subjects a first team of the game whilemarkers 940 represents subjects of a second team of the game.

FIG. 10A shows an example of a central video feed according to anembodiment of the present disclosure. An exemplary virtual reproduction1000-A is illustrated. This virtual reproduction 1000-A includes some orall of the above described virtual reproductions (e.g., virtualreproduction 900 of FIG. 9) but illustrated at different viewingperspective (e.g., birds eye view, wide angle view). For instance, insome embodiments an end user of a remote device 700 is enabled tobetween one or more virtual reproductions of a game, with eachreproduction virtual reproduction having a unique viewing perspectiveand/or unique level of detail within the virtual reproduction (e.g., ahigh quality reproduction that includes one or more optional elementssuch as end zones 908 and a lower quality reproduction that omits one ormore optional elements).

FIGS. 10B and 10C show examples of a first sub-view and a secondsub-view according to an embodiment of the present disclosure. Thetechniques disclosed herein can be applied to virtual scenes or videocaptured by cameras. FIGS. 10A-10C represent actual video frames and arenot necessarily a sub-view of a composed/virtual scene. In someembodiments, the selecting further includes selecting a second subjectin the subset of subjects, other than the first subject. The definingfurther includes defining a second sub-view (e.g., sub-view 1000-C ofFIG. 10C) of the central video feed at the second resolution. In someembodiments, the second sub-view is at a third resolution that is lessthan the first resolution and different than the second resolution.

The central video feed can be captured in one type of orientation (e.g.,landscape), while sub-views are displayed in one or more otherorientations (e.g., all or portrait or some are portrait). In thisexample, the central video feed (FIG. 10A) is captured in a landscapeorientation and each sub-view (FIGS. 10B and 10C) is partitioned in aportrait orientation.

The coordinates of a center of the second sub-view within the centralvideo feed changes over time, without human intervention, in accordancewith a change over time in the position of the second subject asdetermined from recurring instances of the receiving that occur on thesecond recurring basis by the overlapping. Accordingly, thecommunicating further communicates to the remote device the secondsub-view of the central video feed independent of the central videofeed. Thus, an end user of the remote device is enabled to view a firstsub-view dedicated to a first subject and a second sub-view dedicated toa second subject. The first and second subjects can be participating inthe same game or different games (e.g., a first game and a second game).The first game and the second game are played concurrently, arehistorical games that have already been played, or the first game is apresent game and the second game is a historical game. Furthermore, thefirst and second subject can be on the same team or different teams.Moreover, in some embodiments the second sub-view is defined but notcommunicated to the remote device.

In some embodiments, the first subject and the second subject are at thesame position in the spatial region at a first time point (e.g., bothplayers are involved in a scrum for the ball, both players are inpile-up for the ball, etc.). Since the first subject and the secondsubject are at the same position same position in the spatial region ata time point, this causes the first sub-view to overlap with the secondsub-view at the first time point. Further, the first subject and thesecond subject are at different positions in the spatial region at asecond time point. This difference causes the first sub-view to notoverlap the second sub-view at the second time point. Since the presentdisclosure utilizes time-stamped positional information (e.g. telemetrydata 230) to determine a position of a subject in a video feed, insteadof analyzing the optical characteristics of images captured by a camera140, different objects are capable of being independently tracked,without interruption, when the different objects occupy a same location.

The techniques discussed herein may be applied to display more than twosub-views. For example, the plurality of sub-views includes three ormore sub-views such as a view for each player on a side of a footballgame, (e.g., a view for each player in a fantasy team of footballplayers) or on the order of 100 views. Each sub-view in the plurality ofsub-views is centered on a different subject in the subset of subjects.In some embodiments, centering on a respective subject for each sub-viewincludes allocating a tolerance on a position of the subject and acenter of the sub-view. For instance, if a tolerance of the positionalinformation is approximately 15 centimeters, then, a center of thesub-view does not change unless the positional information indicates achange of position greater than and/or equal to 15 centimeters. Thus,any jumps or jitteriness in the positional information is not translatedto the sub-view, ensuring that the sub-view provides a smooth (e.g.,lacking jitter) video stream.

In some embodiments, the central video feed is not communicated to theremote device. For instance, the central video feed is stored in adatabase of the present disclosure. Similarly, each subject for eachrespective subject captured by the central video feed is stored in adatabase of the present disclosure. This storing allows for a collectionof dedicated videos to be curated for each respective subject. Thecollection can then be utilized, for instance, to view each play arespective subject participates in over a period of time (e.g., a game,a season, a career, etc.).

In some embodiments, the plurality of subjects includes a first team anda second team. In some embodiments, the first team and the second teamform a league of teams (e.g., a football league, a soccer league, abasketball association, etc.). The first team includes a first pluralityof players (and the second team includes a second plurality of players.The first team and the second team are engaged in a present game duringthe receiving, the receiving, the overlapping, the selecting, thedefining, and the communicating. The selecting at least a first subjectin the subset of subjects includes selecting each player in the firstteam that is actively engaged in the present game in the spatial region.The coordinates of a center of the first sub-view within the centralvideo feed changes over time, without human intervention, in accordancewith the change over time in the position of the first subject, and inaccordance with a change over time in the position of each other playerin the first team that is actively engaged in the present game in thespatial region, as determined from recurring instances of the receivingthat occur on the second recurring basis by the overlapping.

In some embodiments, the selecting further includes selecting a secondsubject in the subset of subjects, other than the first subject. Thedefining further includes defining a second sub-view of the centralvideo feed at the second resolution. The coordinates of a center of thesecond sub-view within the central video feed changes over time, withouthuman intervention, in accordance with a change over time in theposition of a second subject as determined from recurring instances ofthe receiving that occur on the second recurring basis by theoverlapping). The communicating communicates to the remote device thesecond sub-view of the central video feed independent of the centralvideo feed and the first sub-view.

In some embodiments, the defining further includes defining a pluralitysub-views of the central video feed at the second resolution. Theplurality of sub-views includes the first sub-view (e.g., sub-view1000-B of FIG. 10B). The coordinates of a center of each sub-view in theplurality of sub-view within the central video feed changes over time,without human intervention, in accordance with a change over time in theposition of a corresponding subject in the subset of subjects that isactively engaged in a present game in the spatial region from recurringinstances of the receiving that occur on the second recurring basis bythe overlapping. The communicating communicates to the remote deviceeach sub-view in the plurality of sub-views independent of the centralvideo feed.

Thus, through the systems and methods of the present disclosure one ormore dedicated sub-views derived from a central video feed iscommunicated to a remote device. Each respective dedicated sub-view iscentered on a corresponding subject, which allows for the end-user toview a video feed that is exclusively dedicated that the correspondingsubject (e.g., a video feed dedicated to a favorite player of anend-user). This enables the end user to view a selection of one or morededicated sub-views of subjects according to a selection of the user,such as a selection of subjects included in a fantasy football team ofthe user. For instance, if an end-user is a hopeful professionalathletic, the end-user may choose to view sub-view that are dedicated tosubjects that play a same position as the end-user to use as trainingvideo. Further, since the central video feed is a high resolution videofeed, each sub-view is partitioned without losing significant imagequality. This allows for a single camera to produce any number ofsub-views, which greatly reduces the number of cameras and operatorsrequired to capture a live sports event.

While the present disclosure describes various systems and methods inrelation to a gridiron football game, one skilled in the art willrecognize that the present disclosure is not limited thereto. Thetechniques disclosed herein find application in games with a discrete orfinite state where a player or team has possession of a ball (e.g.,holding the ball) as well as other types of events. For instance, insome embodiments the systems and methods of the present disclosure areapplied to events including a baseball game, a basketball game, acricket game, a football game, a handball game, a hockey game (e.g., icehockey, field hockey), a kickball game, a Lacrosse game, a rugby game, asoccer game, a softball game, or a volleyball game, auto racing, boxing,cycling, running, swimming, tennis etc., or any such event in which alocation of a subject is relevant to an outcome of the event.

The present disclosure addresses the need in the art for improvedsystems and methods for delivering video content to remote devices. Inparticular, the present disclosure facilitates increased spectators'engagement and interest in the live sport event by partitioning a videofeed to segment live player activity.

With regard to expected points evaluation, multinomial logisticregression, or other types of analysis, can be used for estimating theprobabilities of each next event that is possible outcome of a givenplay situation. The next event is a scoring event or a non-scoringevent. The scoring events include a touchdown of a team in possession ofthe ball (7 points), field goal of a team in possession of the ball (3points), safety of a team in possession of the ball (2 points),opponent's safety (−2 points), opponent's field goal (−3 points), andopponent's touchdown (−7 points). Non-scoring events (0 points) includeevents that describe attempts the team in possession of the ball maytake. In one instance, the team in possession of the ball may attempt toadvance the ball to the left, to the right or down the middle in thenext play. In another instance, the team in possession of the ball mayattempt to pass the ball or run the ball in the next play.

Although the foregoing embodiments have been described in some detailfor purposes of clarity of understanding, the invention is not limitedto the details provided. There are many alternative ways of implementingthe invention. The disclosed embodiments are illustrative and notrestrictive.
